Fig. 7: Topographies of the searchlight analysis results showing the temporal and spatial distribution of accuracy values for the binary classification of Interactive vs Cued trials separately for each group (HC/PD ON/PD OFF).

In all groups, fronto-central sites consistently contributed to the classifier’s performance from ∼500 ms before the VP’ correction (time 0). The two dots on each topography represent electrodes Cz and FCz. The scale represents the LDA accuracy over time and electrodes. N PD OFF = 15, N PD ON = 15, N HCs = 15.
